Využití programu GeoGebra pro podporu výuky matematiky na základní škole

GeoGebra is the world's most widely used free software tool for supporting the teaching and learning of mathematics at all levels of schooling, developed by an international team of programmers and education experts. The software itself is complemented by cloud storage and an infrastructure of additional online features and tools available to any of its users. Although GeoGebra itself is increasingly used in our primary and secondary schools, the potential application of this online environment remains somewhat neglected. The aim of this paper is to present the possibilities of using GeoGebra and its online environment in teaching mathematics in primary school, with an emphasis on supporting distance learning. These possibilities are presented through specific teaching materials that the author has created and used in his teaching at primary school. The materials are presented in the context of the teaching situations in which they have been used or for which they are intended, and are discussed in terms of educational content and technical implementation, as well as provided with methodological comments based on the author's personal experience with their implementation
